Rose plant named &#39;Tananaistrua&#39;

ABSTRACT

The new cultivar is a variety of bed rose plant having an upright bushy growth habit with shiny red flowers. The plant exhibits good winter hardiness, resistance to most diseases, and excellent ground covering ability.

BACKGROUND OF THE NEW PLANT

[0001] The present invention includes a new and distinct cultivar of Rosa l. known by the varietal name ‘Tananaistrua’.

[0002] The plant was discovered in 1991 by the breeder in Ueterson, Germany in a selective breeding program designed to produce a hardy, shiny red bed rose plant with good distance display and which is resistant to fungal diseases. The new plant is a selection from a cross of unnamed red floribunda seedlings maintained proprietary by the assignee of the present application. The plant was first asexually reproduced in 1996 and can be propagated asexually on Rosa canina rootstock.

[0003] The variety is distinguishable by its shiny red display, very good winter hardiness, disease resistance, and ground covering ability. Continued observations from the vegetative cuttings in Uetersen, Germany have confirmed that the distinguishing features of this new cultivar come true, remain stable, and are retained through successive propagations.

DESCRIPTION OF THE DRAWING
